Mark James, who held the lead throughout much of the final round, lost first when he three-putted the 17th hole. He was tied for the top spot on 18, but he ran his birdie putt 7 feet by, then missed his par effort.
Wayne Levi also stood atop the leaderboard on Sunday, but an errant drive hurt him on the closing hole.

Unfortunately for Levi, he was not as fortunate as his 6-footer that could have gotten him in the playoff stayed above ground.
